顯示網站最新版本的奇怪 Nginx 問題

我們正在運行 Nginx 1.6.2 並與後端伺服器一起設定為負載平衡器（使用代理）。前幾天注意到，當我在後端伺服器上進行更新時，Web 前端看不到所做的更改。它繼續顯示舊版本。

我們做過的事：

  1. 我們測試過全部瀏覽器會出現相同的結果。
  2. 升級到 Nginx 1.9.4 - 仍然沒有解決問題
  3. 我甚至將 Cache-Control 設為 no-cache，以嘗試排除快取問題。我確實在開發人員工具中註意到，如果我檢查相關文件 - 修改日期顯示舊日期，它不會顯示它們實際更新的時間。
  4. 清除位於 /var/lib/nginx/tmp/proxy/ 的文件

此外，我們正在討論的具體文件是.css和.js文件

最後，如果我們直接連接到 Web 後端之一，它就可以完美運作！（這就是為什麼我們認為它與 Nginx 有關）。

對此的任何建議或建議將不勝感激。
